modules from src/bin/ls, and handling exec(_PATH_LS,..) as a
special case, very useful in an environment where many users
are given chroot access. "~/etc/{s}pwd.db" files are still
needed if uid/gid->user/group translation is desired.
To enable this it must be compiled with the make variable
FTP_INTERNAL_LS defined, either in /etc/make.conf or the
environment.
There are various options documented in i386/conf/LINT, there is more to
come over the next few days.
The kernel should run pretty much "as before" without the options to
activate SMP mode.
There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.
This commit is the result of the tinkering and testing over the last 14
months by many people. A special thanks to Steve Passe for implementing
the APIC code!
When we request sense, don't allow disconnection. This closes a window
where we might allow an overlapped tagged and non-tagged transaction.
The correct fix is to freeze the queue for the target that requests sense
which is what will happen in the new CAM framework.
Our vput calls vm_object_deallocate() --> vm_object_terminate(). The
vm_object_terminate() calls vn_lock(), since UN_LOCKED has been
already cleared in union_unlock(). Then, union_lock locks upper vnode
when UN_ULOCK is not set. The upper vnode is not unlocked when
UN_KLOCK is set in union_unlock(), thus, union_lock tries to lock
locked vnode and we get panic.
(ignored :-() errors for `make depend' in /sys/i386/boot/*. It's
natural for there to be no libraries there and inconvenient to check
for this in bsd.prog.mk.
if SCB Paging was enabled:
disconnect with more data to transfer
disconnected SCB gets paged out
target reconnects so we page SCB back in
target completes transfer so residual is 0
target disconnects
SCB gets reused but not paged out since the residual is 0 (optimization)
target reconnects so we page the SCB back in
we report a residual because of stale residual information.
The fix for this is to set a flag that forces the SCB to be paged back
up to the host if we page in an SCB with a residual

Fix another bug: if argv[0] is NULL, garbadge args might be added for
shell script
